I guess for "UTP" cable you mean the ethernet connection (being usually the
connection toward the physical camera coaxial).

In order to understand whether no data is neing transmitted anymore, you can
use the "on-timeout" signal in rtpbin:

http://www.gstreamer.net/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-gstrtpbin.html#GstRtpBin-on-timeout

Unfortunately, this timeout value appears not to be directly tunable, being
computed as the minimum between 5s and 5 times the (RTCP?) reporting time.
The latter is not directly tunable and should require some negotiation at
signaling level (I guess you're using RTSP or SIP) to get prompt reaction
for the receiving sw.
